As a developer, I want to utilize exit codes to differentiate failures of the process vs. validation errors

Is your feature request related to a problem? Please describe. Process returns exit code 1 when validation process completes successfully but detects errors

Describe the solution you'd like Exit code 1 implies process failure (failure to find file, failure to parse xml, etc) Exit code 2..n implies validation error(s) (depending on whether it's useful to differentiate sub-cases)
